Mineral Resources Program
We are the Nation’s primary source of scientific information about the full life cycle and supply chains of mineral resources. Our science is essential to responsibly managing natural resources and to procuring minerals needed to sustain and advance modern manufacturing, technology, infrastructure, and low-carbon energy production.

Widespread occurrence of former anhydrite phenocrysts in Laramide-age magmas related to porphyry-skarn Cu mineralization at Santa Rita and Hanover-Fierro, New Mexico, USA
Reports of magmatic anhydrite are relatively rare, with only ~30 occurrences documented worldwide so far. However, magmatic anhydrite saturation is difficult to recognize because anhydrite decomposes rapidly in near-surface environments. In most cases, only anhydrite inclusions shielded within other phenocryst phases were able to survive. Alternatively, since anhydrite phenocrysts...
Geophysical characterization of an alkaline‑carbonatite complex using gravity and magnetic methods at Magnet Cove, Arkansas, USA
The Magnet Cove alkaline‑carbonatite complex (MCC), located in the Ouachita Mountains of south-central Arkansas in the United States, hosts an extensive variety of rare rock types and critical mineral resources with physical properties (density and magnetization) that contrast significantly with the sedimentary rocks into which they have intruded. Newly acquired ground-based gravity and...
Rock sample photogrammetry protocol
This step-by-step protocol describes the photogrammetry process used by the U.S. Geological Survey Spokane Imaging Lab (SPIMG) lab to create 3D models of geologic samples. Steps related to photographing small objects are applicable to photogrammetry in general, however, SPIMG-specific steps involving lab hardware and software may not be.

Increased Mercury, Reduced Insect Diversity, and Food Web impacts from Historical Mercury Mining
U.S. Geological Survey scientists are seeking to understand the impacts of mercury mining on headwater streams, organisms, and food webs, focused on potential effects from historical mining in central Idaho. Mercury associated with mine waste can leave a legacy of contamination that continues to impact stream health in culturally and ecologically important headwater streams after mining activities...
What are Critical Minerals?
Critical minerals are essential to the economy and national security of the Nation and have supply chains that are vulnerable to disruption. The USGS leads the government in developing the List of Critical Minerals and provides crucial and rich information about critical mineral availability, supply chains, and economic impacts. The USGS uses a cross-sectoral and data-driven approach to developing...
Earth MRI Progress
Earth MRI is a national effort to map critical mineral resources needed to drive the U.S. economy and national security, searching below ground and in tailings from old mines. As directed by the Energy Act of 2020, the U.S. Geological Survey has identified 50 critical minerals essential to the U.S. economy and national security, with a supply chain vulnerable to disruption. We partner on this...
